Italian inventor and creative genius Gianluca Gimini found the perfect way to upcycle and resell used toothbrushes.He calls them "rethINK pens," and I would totally buy one given the opportunity!Gianluca started saving his used toothbrushes "because the handles looked so nice and new" and he felt wrong just throwing them away.Makes sense, I've often thought of the millions of plastic toothbrushes sitting in landfills forever and ever and ever.He created this amazing colored pen project that is cute, marketable, and totally green.Best of luck to Gianluca and I will be looking for these on the selves at my local CVS soon!
